Description of the Related Art Conventionally, as a container for accommodating a spool for a bonding wire, a container main body integrally provided with an upwardly bulging fitting ridge for fitting a cylindrical spool, and a container body outer edge peripheral wall ridge are fitted. There is known a spool case including a cover body (for example, Japanese Utility Model Laid-Open No. 54-103747). In this spool case, the fitting ridge in the container body is formed in the shape of a circular truncated cone, so that the spool is firmly attached and fixed to the fitting ridge.

の外周壁に接触して損傷する等の不具合を生じた。However, due to manufacturing reasons, the inner diameter of the spool may vary, and according to the above-mentioned conventional structure, if the spool diameter is too small, the inner peripheral surface of the spool and the fitting ridge will come into close contact with each other over a wide range. When the spool was taken out, it was difficult to pull it out, and when trying to pull it out with a strong force, the bonding wire wound around the spool contacted the outer peripheral wall of the container body and was damaged.

ことがあった。On the other hand, there has been proposed a device in which a plurality of projecting edges that bulge outward are integrally formed on a peripheral wall at predetermined intervals (for example, Japanese Utility Model Laid-Open No. 1-83769). However, since the projections are often small and difficult to form, there are cases where the shapes vary and the contact with the spool does not go well. In addition, the thickness of the protrusions is often thin, resulting in poorer durability than other parts,
The number of repeated uses may be limited by this protrusion.

箇所で容器本体に堅固に固定される。BEST MODE FOR CARRYING OUT THE INVENTION According to the spool case for a bonding wire of the present invention, a portion where the spool is fitted from the inner periphery near the bottom surface and a portion where the spool flange is fitted from the outer periphery are formed in the container body. Therefore, the spool is 2
It is firmly fixed to the container body at some point.

突起でもかまわない。The portion where the spool and the container body fit together does not have to cover the entire circumference of the spool, regardless of the inner circumference and outer circumference. Therefore, the bulging ridge fitted to the inner peripheral surface of the spool may be not only a truncated cone shape but also a plurality of protrusions inscribed in the spool.

るのが望ましい。When the size of the fitting portion of the inner surface of the spool is too large compared with the diameter of the spool and the spool is fixed to the container body without the flange coming into contact with the outer fitting portion, a large area of the inner surface of the spool is obtained. Since it is difficult to take out the spool due to the close contact with the fitting portion, it is desirable that the dimension of the inner peripheral fitting portion is slightly smaller than the spool diameter in consideration of variations in spool diameter.

ることは何ら差し支えない。It is desirable that the side surface cross-sectional shape of the surface fitted to the inner peripheral surface and the outer peripheral surface of the spool has, for example, a V-shaped taper so that the spool can be easily inserted and removed. Further, in view of the gist of the present invention, there is no problem in forming a slit or a recess for fitting a flange on the outer peripheral fitting surface.

For one thing, the end of the wire may be attached to the outer flange through the notch in the spool. In the case of this form, when the recess is formed in a part of the portion where the flange of the container bottom is in contact, it is possible to prevent the contact between the container body and the wire by disposing the wire sticking portion in the recess,
It is desirable that the recess be provided.

果があり、繰り返し使用に十分耐え得る。As described above, in the bonding wire spool case of the present invention, the spool can be firmly fixed because it is supported at two places, the inner peripheral surface of the spool and the outer peripheral surface of the flange, and the outer peripheral surface of the flange can be fitted. This also has the effect of suppressing the close contact of the spool inner peripheral surface fitting portion with the container body over a wide range, so that it is easy to take out. For this reason, when pulling out the spool, you have to pull it out with a strong force and accidentally touch the wire, or when the spool case lid is opened due to insufficient fixation between the spool and the container body, you may accidentally drop the spool. It has the effect of preventing accidents and can withstand repeated use sufficiently.
